Product Information

4 Speed XT- Works Fast On Toughest Weeds

4 Speed XT Selective Herbicide combines four active ingredients, triclopyr, 2,4-D, pyraflufen and dicamba for a powerful and fast control of more than 100 broadleaf weeds. 4 Speed XT is a post emergent spray that may be used on ornamental turf lawns (Residential, Industrial, and Institutional), golf courses, parks, roadsides, sod farms and similar sites. As a fast acting and effective weed killer, you will start to see symptoms of injury to the weeds with 1-2 days of application in such hard-to-kill weeds, such as oxalis, spurge, wild violet and wild geranium.

Application Recommendations

You may apply 4-Speed XT as a post emergent spray as a broadcast or spot treatment. Spray actively, young weeds.To minimize drift, use a medium or coarser spray nozzle. Do not spray during temperature inversions or at wind speeds over ten mph.

Use Directions

Bermudagrass - If Bermudagrass is dormant, up to 4 pints per acre may be used. However, some hybrid Bermudagrasses may be sensitive to this product. Contact your local extension service weed control specialist.

Warm Season Turfgrass - Use reduced rates if grass is stressed from heat or drought. Exercise care when applying during growth stages from dormancy to green-up and from green-up to dormancy. Some temporary discoloration may occur on warm season grasses.

When mixing with fertilizer - Higher water volumes may be used when tank mixed with a turf fertilizer. Follow fertilizer labels for proper amounts to add.

Bentgrass - Apply on closely mowed Bentgrass, preferably in May or mid-August through September. Slight turf yellowing will disappear after about one week.
